Abstract

L'invention concerne un procédé de détection de saturation d'un transformateur de courant comprenant :
- une étape de détection d'un défaut de la forme d'onde du courant secondaire du transformateur ;
- une estimation du flux magnétique dans le secondaire du transformateur au moyen d'une intégration du courant secondaire pendant une fenêtre temporelle partant de la détection dudit défaut ;
- une comparaison du flux magnétique ainsi estimé avec une valeur de seuil, la saturation du transformateur étant détectée sur franchissement de ladite valeur de seuil par ledit flux magnétique.
